The project aimed to: assess the health status of mother seed trees; document and describe the decay/cull and stress indicators of trees; and provide/prescribe management recommendations/or the options for tree rehabilitation, maintenance and protection.

There were seven (7) active regional implementors of the project namely Regions CAR, 1, 2, 3, 6, 7, and 8.which were then mentored and supervised. These regions produced their updated list of mother seed trees which were assessed of their health status following the DENR form for Pest and Disease Surveillance.

Generally most of the seed trees assessed were healthy with the exception of the centennial Rain trees in CAR, Region 1, 2 and 3. Some cull and stress indicators of decay are evident which served as entry points for wood decay fungi and insects. Among the common indicators are presence of termites, butt and stem wounds/openings, branch stubs, presence of iron nails, presence of fruiting bodies, presence of saprophytic/parasitic vines, dead branches and absence of barks-exposing the cambium. Management for tree rehabilitation, maintenance and protection was prescribed vis-a-vis decay/cull and other stress indicators.

A techno-bulletin titled "Health assessment of trees as seed sources and the importance of seed production areas" was prepared.
